Title: Image forming apparatus
Inventor: SAMEJIMA KEISUKE
IPC: G03G21/14
Filed: 2007-08-09
Abstract: <P>PROBLEM TO BE SOLVED: To recover from deterioration of an image level of an image forming apparatus continuing for a certain period of time.  <P>SOLUTION: When a power source switch is turned ON, the pressurized state of a fixing belt unit and pressure roller or their released state is detected. When the pressurized state is detected, a process enters a start-up sequence for recovering an image level. When a released state is detected, a pressurized state is set and the process enters a regular start-up sequence. Even if the AC power source of the image forming apparatus is shut off in terms of hardware besides the sequence described above, the process enters an operation sequence in which the fixing belt unit and pressure roller is released, before the output of a low voltage power source is shut off. A power accumulation means that has electric charges sufficient only for releasing the pressurized state is used as a low voltage power source.  <P>COPYRIGHT: (C)2009,JPO&INPIT
